EXPERIMENTAL HEAT TREATMENT OF M-60 MACHINE GUN BOLTS,
Abstract
Presented is the development and testing of carburizing and heat treating procedures for a series of experimental M-60 Machine Gun Bolts manufactured of 9310 alloy steel. Acceptable case and core properties were obtained with minimum heat treat distortion by quenching the subject bolts direct from a 1700 F gas carburizing treatment into a still salt bath at 400 F, followed by -100 F refrigerating and 350 F tempering treatments. Comparative low temperature impact data were obtained on carburized 8620 and 9310 material in oil quenched and 400 F salt quenched conditions. (Author)
